1. With your partner, think of as many examples of inclined planes as you can. Record your list. Handicap Ramp Slide Parking Ramp
Hills Car Ramp
Propeller Escalator
Grocery Ramps Stairs

2. Select a length for the inclined plane.
Record the length, height, effort force and indicate whether or not it was successful.
Repeat using various lengths.

3. From your chart of data, find the maximum effort our crew member can sustain to pull the stone up the inclined plane. What is the length of this inclined plane? [408n] 3.62m
4. Would this be the ideal length to use for the inclined plane? Yes, it would be an ideal length to use for inclined planes.
5. What other factors might you consider?
Smooth Surface
6. Defend your choice for the ideal length. Give your reasons in complete sentences. I think smooth surface would be the best surface and its easier to push something or move something with smooth surface.
7. Transfer the data for length and effort from Table 1 onto Table 2.

8. Calculate the amount of work done to get the stone to the top of each inclined plane. Remember: Work = Force applied X distance mass is moved.
